for now the unit will be connected to an older analog tv in order to receive local digital signals, which should give me better reception than the present analog. would also prefer that the stb would be able to connect to the tv via rf connection so that the wife would not have to tune to another input on the tv. she would also prefer that the stb be black to match the other ht components. regarding future tv upgrade, been looking at the samsung dlp units. are all stb's compatable with all tv's? any special tricks that I would need to understand/know?
